scikit-learn - Wikipedia
scikit-learn（サイキット・ラーン、旧称: scikits.learn）は、Pythonのオープンソース機械学習ライブラリ[2]である。サポートベクターマシン、ランダムフォレスト、勾配ブースティング、k近傍法、DBSCANなどを含む様々な分類、回帰、クラスタリングアルゴリズムを備えており、Pythonの数値計算ライブラリのNumPyとSciPyとやり取りするよう設計されている。 教師あり学習と教師なし学習に対応している。ただし、強化学習・深層学習・グラフィカルモデル（隠れマルコフモデルなど）・シーケンス予測には対応しない方針となっている[3]。 概要[編集] Scikit-learnプロジェクトは David Cournapeau によるGoogle Summer of Codeプロジェクト、scikits.learnとして始まった。名前は「Scikit」 (SciPy Tool
Confusion matrix
Confusion matrix# Example of confusion matrix usage to evaluate the quality of the output of a classifier on the iris data set. The diagonal elements represent the number of points for which the predicted label is equal to the true label, while off-diagonal elements are those that are mislabeled by the classifier. The higher the diagonal values of the confusion matrix the better, indicating many c
Underfitting vs. Overfitting
Underfitting vs. Overfitting# This example demonstrates the problems of underfitting and overfitting and how we can use linear regression with polynomial features to approximate nonlinear functions. The plot shows the function that we want to approximate, which is a part of the cosine function. In addition, the samples from the real function and the approximations of different models are displayed
PowerTransformer
PowerTransformer# class sklearn.preprocessing.PowerTransformer(method='yeo-johnson', *, standardize=True, copy=True)[source]# Apply a power transform featurewise to make data more Gaussian-like. Power transforms are a family of parametric, monotonic transformations that are applied to make data more Gaussian-like. This is useful for modeling issues related to heteroscedasticity (non-constant varia
RobustScaler
RobustScaler# class sklearn.preprocessing.RobustScaler(*, with_centering=True, with_scaling=True, quantile_range=(25.0, 75.0), copy=True, unit_variance=False)[source]# Scale features using statistics that are robust to outliers. This Scaler removes the median and scales the data according to the quantile range (defaults to IQR: Interquartile Range). The IQR is the range between the 1st quartile (2
